摘要： A system and method for making a biomaterial device includes a support structure providing a shape for a biomaterial device. At least one applicator has a supply of biomaterial solution and is positioned along the support structure. The at least one applicator forms a biomaterial fiber by applying shear force to the biomaterial solution and delivering the biomaterial fiber to the support structure. A controller causes relative movement between the support structure and the at least one applicator, and the biomaterial fiber is arranged on the support structure according to the relative movement to form the biomaterial device. The biomaterial may be silk fibroin which may be wound onto a reciprocating and rotating mandrel. Control over the properties of the biomaterial device is achieved through appropriate selection of material processing, winding strategy, and post-winding processing.

摘要： The invention provides a method for forming an immobilized agent gradient within a 3-dimensional porous scaffold. A 3-dimensional scaffold formed from a biocompatible material is provided. The surface of the scaffold and/or the agent is activated so as to allow binding of the agent to the scaffold. The activated scaffold is contacted with a solution containing the agent. Contact with the solution is maintained for a sufficient period of time to allow diffusion of the solution through a portion of the scaffold, thereby forming a desired gradient of the agent through the 3-dimensional scaffold.

摘要： The present invention discloses a method for producing polymers in a microscale device. The system utilizes a symmetrically branched system of microchannels interconnecting a plurality of loading decks and re-action chambers. The fluid flow is manipulated by the placement of capillary check valves, mixing areas, and microcomb filters. The system provides for cascading enzymatic biosynthesis pathways wherein any variety of enzymes and reactants can be introduced into the system to produce a final product.
